COMBINATION VISE AND GRIPPING TOOL Filed Dec. 12. 1927 Patented 0a. 29,1929 UNHTED STATS mam serene errics AUSTIN A. BENEDICT, OF MERRILL,WISCONSIN, ASSIGNOR OF THIRTY-FIVE PER GENE TO DAVE P. RAJEK, OFMERRILL, WISCONSIN COMBINATION VISE AND GRIPPIN G TOOL Applicationfiled; December 12, 1327,

This invention relates to a combination vise and gripping tool.

Objects of this invention are to provide a novel form of gripping toolwhich is adapted to engage bolts, keys, or .pins, whether or not anyheads are provided, so that the device will readily remove bolts evenwhen the heads are broken ofi.

Further objects are to provide a device of the type outlined above inwhich interchangeable jaws are provided for enga ing work of differenttypes, and in which a jointed handle is provided which may be operatedto force a cam or conical member between the cam faces of the jaws toforce them into binding engagement and cause their serrated edges tobite into the bolt or pin, and further to so construct the device thatthe handle may be swung to the side when needed, either for ease inmanipulation or for greater levera e.

Embodiments of the invention are shown in the accompanying drawings inwhich:

Figure 1 is a side elevation of the device with parts broken away and insection;

Figure 2 is a sectional view on the line 2-2 of Figure 1;

Figure 3 shows a further form of jaw.

Referring to the drawings. it will be seen that the device comprises abody portion having a pair of spaced U-shaped arms 1 joined to a head 2.A relatively large screw 3 is threaded through the head 2 and carries aconical head 4 at its outer end. The inner end of the screw is pivoted,as indicated at 5, to a T-shaped handle 6 so that the screw may berotated either by gripping the handle while in line with the screw orelse by rocking the handle laterally of the screw and thereby obtaininggreater leverage.

Between the arms 1 of the device a pair of jaw members 7 are pivotedupon removable screws 8 and are urged apart by means of a U-shapedspring 9. These members are in reality jaws and are provided with grip-Serial No. 239,517.

In using the device, the jaws are slipped over the object to be removedand thereafter the screw is screwed inwardly, thus forcing the cam facesof the jaws apart and causing the jaws to actually bite into the memberto be removed.

Other forms of jaws may be used, for inv stance, as shown in Figure 1,alligator or elongated jaws, indicated in dotted lines at 12, may beemployed. In addition to this, the

form of jaw indicated in Figure 3 by the ref erence character 13 may beemployed. This j aw is formed by bending the jaw portion over oroffsetting it with reference to the plane of the body portion 14. Thebody portion 1s provided with a cam face 15 similar to the cam faces 11,previously described. The jaw 13 may be provided with a straight row ofser-' rations 16. I

It will be seen that a simple type of combination vise and clamping toolhas been shown and it will be seen further that the device maybe'manipulated to engage widely different types of work and to securelyhold the work locked to the jaws so that bolts may be removed eventhough their heads may be broken ofi. Further, the device may engagepins, keys, or other members with the utmost ease.

Although the invention has been described in considerable detail, suchdescription is intended as illustrative rather than limiting as theinvention may be variously embodied and as the scope of such inventionis to be determined as claimed.

I claim:

A gripping tool comprising spaced U- shaped arms, a head joining saidarms at one end, a relatively large screw threaded'through the head, aconical end on said screw between UK I the arms, a T-shapedhandlepivoted to the end of said screw, a pair of jaw members pivotallymounted between said arms, gripping jaws at the outer ends of the .jawmembers, cam portions at the inner ends, of said jaw members, roundedserrated faces on said jaws and a U-shaped spring arranged between saidjaw members with its ends engaging the gripping jaws to normally urgethem apart.

In testimony that I claim the foregoing I have hereunto set my hand atMerrill, in the county of Lincoln, and State of Wisconsin.
